Specification of `Letters Patent.

Patented Dec. 22, 1911.

Application led April 7, 1914. Serial No. 830,281.

To all whom t may concern.'

Be it known that I, CHARLES L. Sum, of Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Distillate-Condensers and Steam-Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in distillate condenser and steam generator, the object being to provide means whereby theheat of the distilled vapor passing from the still, may be used to generate the steam which may be required in the distilling process, and it consists in the parts and combinations of parts as will be more fully explained and pointed out in the claims.

rlhe accompanying drawing is a view partly in side elevation and partly in section of my improved apparatus.

1 represents a still, which for the purpose of convenience, I will refer to as an oil still. The still is mounted in or over aI furnace, and is provided at its top with a dome 8 communicating with a vapor pipe 4 through which all the vapor generated in the'still passes into the generator or water heater 5, at the top thereof. This generator or heater is made of boiler metal of any shape in cross section and is divided into three compartments by two heads 6, so as to form water spaces 7 at the ends, the two end compartments being connected by the water tubes 8, through which the water is `free to pass from one end compartment to the other. The vapor enters the generator 5 between the two heads 6, and passes around and between the water tubes, and is preferably deflected, from a straight passage between the tubes, by bafie plate 9, so that the hot vapor on its passage from the still to the condenser 10, passes around and in contact with water tubes and heats the water to a temperaturev sufficient to generate steam.

One or more of the tubes 8 in the generator are located above the normal water level which is indicated by the dotted line .fc-a5 so that the steam will have free and unrestricted passage from one end compartment 7 to the other, and the water space or compartment 7 at one end of the generator, is connected by a pipe 11, with the steam pipe 12 which leads from a steam boiler (not shown) into the still and is connected to a superheating coil 13 within the still, whereby the steam will be heated toa high temperature before coming in contact with the. oil, the lower pipe or pipes of the superheating coil being` perforated for the escape of the steam into the still. The st'eampipe l2 preferably passesthrough the vapor plpet and dome 3, and the vapor pipe is provided, preferablyV adjacent the generator 5, with a safety valve 14, which prevents the accumulation of excessive pressure within the generator and also within the still.

Located within the end compartment 7 of the generator are the floats 15 and 16, one of which 15, regulates the valve 17 controlling the passage of steam through pipe 12 from the steam boiler, while the other one 16, controls the valve 18 in the water supply pipe 19, which discharges into the generator In the present-instance I have shown the water supply pipe leading from a steam pump 20, but in most refineries this pump would not be necessary or used, as there would Abe a main water feed line to all the stills, the water being under sufficient pressure to pass into the generator directly from the main feed line. I have also illustrated a water pipe 21 leading from the condenser l() to the pump 20, for supplying water to the latter, which would be omitted, when the water pipes 19 are connected with a main feed line pipe. The steam pipe 11 connecting the steam'space in the generator 5 with the steam pipe 12, is provided with a check valve 22 which prevents the steam in pipe 12 from entering the ygeneratorln the operation of the apparatus, the valve 18 admits water into the generator until it is lShut oflrvby the float 16, which is so located to actuate balanced valve 18 and cut off the supply before the top water or steam tubes 8 are covered, so as to permit of the free passage or interchange of steam between the two end compartments 7. By the time this high water level has been reached in the generator, the float 15 will have been lifted so as to actuate balanced valve 17 in a direction to permit steam from the boiler to pass freely through pipe 12 and into the still. The hot vapors passing from the still to the generator, heat the water therein sufficiently to generate steam which passes from the generator through pipe 11 into steam pipe 12. 4This. generation` of steam in the generator causes the water level therein to drop and thus actuate valve 17 in a direction to cut oil the steam supply from the boiler, and when a somewhat slightly lower level is reached iioat 16 will drop and thus open balanced valve 18 in water pipe 19 so as to raise the water to normal level, and the operation is continued while the apparatus is in operation. Should there not be suliicient heat in the vapor passing from the still to vaporize suiicient of the water to materially lower the level. of the latter the ioat 16 will hold valve 18 closed, thus throwing the pressure on the pump, which pressure acting on the automatic regulator 23, closes valve 24 in steam pipe leading to the pump and thus automatically stops the pump until the pressure in pipe 19 is reduced by the escape of some of the water into the generator, at which time valve 24 will be opened by the regulator 23 and the pump again started. v

While I have shown the steam pipes from the generator discharging into the still, it is evident that the generator may be used for heatingboiler feed water heating oils or the steam generated therein used at points outside of the still. It is also evident that other changes mlght be resorted to in the relative arrangement of parts shown and described without departing from the spirit v and scope of my invention. Hence I would condenser in communication with said middle compartment, means for automatically supplying water to one end compartment and an outlet from one of-said end compartments.

2. The combination of a still, a condenser, a water heater divided into three vertical compartments, the two end compartments` being connected by water tubes, a va or tube leading from the still to the mid le compartment, a tube leading from the middle compartment to the condenser, a water supply pipe, a oat in one of said compartments for automatically regulating the su ply of water to said heater, a steam pipe eading to the still and a pi e connecting one end compartment of the eater with the steam pipe.

3. The combination of a still, a condenser, a steam pipe leading to the still, a water heater divided into three vertical compartments, the two end compartments being connected by tubes, a water supply pipe leading to an end compartment, an outlet pipe leading from an end compartment to the steam pipe, two floats, one for controlling a valve in the steam pipe and the other for con trolling a valve in the water supply pipe, and a pipe leading from the middle compartment of the water heater to the condenser.

4. The combination of a still, a condenser, a steam pipe leading to the still, a water heater divided into three vertical compartments, the two end compartments being connected by tubes, baliie plates intermediate the tubes, a water supply pipe leading to an end compartment, an outlet pipe connecting an end compartment with-the steam pipe, two lloats, one for controlling a valve in themsteam pipe and the other for controlling a valve in the water supply pipe, and a pipe leading from the middle compartment of the water heater to the condenser.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
